A radioactive substance decays in such way that the amount of mass remaining after t days is given by the function
, where m (t) is measured in grams.
m(t) = 12e-0.0671
1. Find the mass at time t = 0.
2. How much of the mass remains after 30 days? (Round to
nearest tenth of a gram)

the answer is c

hope this !

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
